The guard 1, as

seen fromthe end, as in Fig. 2, ispreferably of oblong shape, ythe ends being rounded, and in "one end of the' body of the guard f is formed a chamber 13, to be occupied by the holding the studB. in place, andin this renut 7 when the guard is in use, while in the opposite end is mounted the rotary cylinder of a lock adapted tobe manipulated by a key 15.` The lock may be of any suitable construc-v tion,that shown being formed with a cam .pin 9 at the inner end of the rotary cylinder 2 that is adaptedjto throw aplunger 8 that is preferably movable in a path at right angles to the axis ofthe cylinder, and the free end of the plunger .extending into the chamber 1,3

and being adapted to lie in Vthe circumfcrea tial groove 6 in the nut 7. A spring 11 acts upon the plunger and tends tomove it into position to engagewith the nut. vA screw or pin 3 seated yin the body of the guard and engagingwith a groove formed in the pe riphery` of the lock cylinder 2, limits the movement of the latter in a well-known man- The chamber 13 is open-ended at one (the inner) face of the nut guard, so that the latter may be readilyapplied to the nut, While theopposite end of the-chamber is closed bythe integral wall of the guard constituting its front exposed face. A short stud or projection l10 Iextends from the inner 'face `ot thenut .guard and is adapted to 'enter the f apertures'c when the guard is applied.

' In Fig. 3 kis shown an embodiment'of the present invention somewhat different from that representedin -F ig. 1.` Referring to such view jit' willv be seen that the opening c2 through the lower band section a is considerably larger "than the corresponding aperture ain Fig. 1 being of a size large enoughfto permit the nut'7 :topass through it.y This, permits the nut to be screwed on to the threaded stud B sufficiently far to engage -w1jth-the inner face of the portion @ofthe upper band `section a thus uniting the stud securely to such vsaid .sectionA With thisv arrangement the special nut 7 vis supposed to remain Y permanently Vin Vclamping position,

spect it diikfers from the special nut 7of Fig.

1 which is removed from the stud each time the band A is opened.

. The nut 7 is provided with a circumferential groove 6. lThe conical portion 5 of the nut 7 is at the eXtreme end of the latter as indicated, a cylindrical portion 14 that bounds the groove 6 on one side being immediately inside the conical part The guard that houses the nut 7 and also encases the loclcQ is represented as being secured to the portion C of the bandV section a by a-bolt or screw, of lwhich one or a'plurality may be employed as is most desirable. rlhe head of the connecting screw or bolt is adapted to enter a recess shaped to receive it formed inthe opposite portion C of the band a. yfhisprojection 10 takes the place of the projection 10 shown in F ig.- 1 and operates to preventA any sliding Vmovement of the two :tree end portions of the band when locked to-yM gether. l

The tire lockingdevice represented in Fig.

- 1 iszused as follows:

When a tire is to be locked upon its rim,

l or wheel telly, the two sections of the band A, T

are' o ened turnin' on the hino'e a the"r band is placed over the tire, the ends of the band sections brought together causing the screwthreaded end of the 4stud B to pass Vthrough the aperture c, and then the nut 7 is.

screwedl upon the exposed end .of the stud."

This operation causes the band to encircle the tire and rim or telly, as a loop held closed by the nut. The nut guard andy lock' are then applied, the lock cylinderhaving been turned.- by the key to throwthe plunger or bolt 8 inwardly, that is with its end entering the chamber 3. Vith the form of lock shown the key `may now be removed and the spring 11 will hold the bolt in its thrown or lockingy position, permitting it, however, to be moved inwardly,as byengagement with the cone y portion Aoi the nut 7 as the guard is placed over the nut. As soon as the end of the plunger passes the cone 5 and comes opposite the groove 6 the spring 1'1V moves the plunger, causing it to enter such groove and locking the guard in -position covering and enclosin the nut, andthe plunger of the lock holds the guard in this covering position until the lock is manipulated by the key 15 to withdraw the plunger. As the guard comes into position covering and 'enclosing the nut, the stud or 'proyection 10'enters`the recess c, or one of them if the stud is short, and this engagement of the nut guardand lock'carrier with the tire band prevents its movement relative to the nut in rotative directions, as well as prevents h one section C to slide on the other. Without thel use Vof the projection 10 the guard would be locked `in position covering the nut and there secured, even though the guard might then be free to rotatel about the nut, the end of the bolt or plunger 8 traveling in the groove 6, but this might be objectionable .and

, vided toprevent suchnrelative movement.

therefore the stud or'projection 1() is pro- In using the form of invention illustrated "in Fig. 3 the special nut 7 does not have to be removed from the stud and applied thereto each Vtime the band is opened or closed, but

Y is screwed tightly upon the bolt or stud B 1 oncekand for all. When the band is closed about a tire the nut guard is carried over the nut 7 and lockedthereto the same wayV that the guard is lockedV tothe nut'7of Fig. 1, and when so locked the band is held about the ytire until the lock is manipulated ,by the use of the proper key to separatel the plunger 8 from the circumferential groove in the spe-T cial nut, `whereupon the guardmay bevre-v moved and thelocking band opened.

A spring 4 is shown in Fig. 1 between thev endy of the nut 7 and the vwall of ythe housing closing the outer end of the chamber 13, to prevent rattling of the guard andthe parts which itv carries, the spring being compressed as the guard is'placed over the nut and there locked in place. The spring 4;, however, may be omitted if not desired.

Itis obvious to those skilled in the art that the details of construction as well as the precise arrangement of parts of the tire locking means `herein described vmay be varied without departing from the spirit of the invention; as for instance, to cite but a single illustration, by making the band of a unitary piece, as illustrated in the patent to C. A. Godshalk, 1,570,477 of yJanuary 19, 1926, instead Vof two sections,L as illustrated; and therefore it is to be understood that the iny vention is not limited beyond lthe scope of gage with grooved portion ofthe nut through the action of the spring when such j prising a nut adapted to be applied to a screwthreaded'stud the nut having an exterior circumferential groove, and a conical portion toward the end of the nut beyond the groove,

a guard for covering and housing the nut havinga body inoneportion otwhich is a cavity for the nut and in another portion, to one` side of the nut cavity, another cavity for a lock and a lock having a plunger the end of which. extends into the nut chamber'of the housing, the plunger being Aspring-operated and arranged to yengage with the conical part of the nut and to :be movedbackward against the action of the spring as 'the guard is applied to the nut, and is also adapted to engagev sok with the groove in the nut through the action j of the spring when its end passes the said lconical part of the nut and the vguard vcomes to proper position tohouse the nut.
